I also have this in my feathercoin debug.log

Thanks for that investigation work @Aciddude as this seems totally consistent with @Ghostlanders warnings of mixing v2 and v4 database types I have posted in Technical developments to fix this issue.

0.9.3.2 should not have been released untill some issues have been ironed out.

So it needs to be made backwardly compatible, for this release. It is being used as a minor release but causing major release issue…

Good catch @aciddude

When we are ready ,I suggest enforce a hard fork for update to 0.9.3.2 or 0.11.2

@lizhi A hard fork just for v4 is a waste of time.

wrapper

@Lizhi We can do the fork when we are ready, and we could be ready soon.

We need tidy up 0.9.3.2 and create a final 0.9.3.3 - It will not take long …

The we can start to check 0.11 is ready for change over.

@ghostlander Do you want to implement BIP102 with V4 ? This is not difficult, can be completed.

ghostlander

@lizhi What makes you think FTC needs 2MB blocks? The current ones are 95%+ empty. Besides FTC is 10x faster than BTC.

Wellenreiter

I agree with @ghostlander :)

There is also a drawback, that the block chain will consume even more disk space and synchronization will take more time

wrapper

There is the possibility to add 2MB when needed? I understan v4 does a lot of pruning and in future the blocks are likely to be compressed

If I recall it correctly, Ufasoft’s multi-currency client stores the blockchain in a format of their own in which it gets compressed, so you might switch to it and see a small decrease in the usage of your hard-drive.

What we usually do is proportional, what about setting the FTC Block size to 200K? (as a compromise)

I agree with @Ghostlander - 2MB block will take longer to transmit and could cause issues building 1 minute block.

I will re-iterate that 30% of blocks have transactions currently, this shows interest and use. The idea is to make FTC usefull and that could be for the smart contract features, with unlimited used, even more than money…

So I also I agree with @Lizhi that it as advantageous to change now, while that is still manageable.
